Mechanical wave propagation in carbon nanotubes driven by an oscillating tip actuator

We investigate the mechanical wave propagation in single-walled carbon nanotubes (SWNTs) induced by two oscillating tips, using molecular dynamics simulations. We found a mandatory correlation condition between the tip oscillation frequency and magnitude in order to generate a quasi-steady-state sta...

Zusammenfassung:We investigate the mechanical wave propagation in single-walled carbon nanotubes (SWNTs) induced by two oscillating tips, using molecular dynamics simulations. We found a mandatory correlation condition between the tip oscillation frequency and magnitude in order to generate a quasi-steady-state standing wave with a characteristic wavelength and frequency changing with the tube radius, but independent of tip conditions. Our findings suggest the possibility of using SWNTs as nanopumping systems for potential applications of fluid transport and drug delivery.
